[0035] Here, the technical solutions in the embodiments (or "implementations") of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first" and "second" in the embodiments of the present disclosure are used only for descriptive convenience and should not be understood as indicating or implying relative importance.

[0037] With the development of society and economy and the improvement of people's living standards, household appliances such as refrigerators and freezers have become indispensable in people's daily lives. During the manufacturing stage, refrigerators and freezers are usually assembled from multiple parts to produce refrigerators.

[0038] In the related art, refrigerators usually transport the cold air generated by the refrigeration system to the freezer and refrigerator compartments through air ducts. However, due to the limited installation space of the air ducts, after installing the freezing duct, it is difficult to connect the freezing duct to the refrigerator compartment from above, which will cause inconvenience in the installation of the air duct.

[0039] Based on this, the present disclosure provides a cabinet assembly 100 and a refrigerator 10, wherein the air duct of the refrigerator 10 is easy and convenient to install.

[0040] like Figure 1 as well as Figure 2 As shown, in some embodiments, the refrigerator 10 includes a door assembly 200 and a body assembly 100. The body assembly 100 is provided with a accommodating cavity 111. The body assembly 100 includes a refrigerated liner 120 and a frozen liner 130 spaced apart in the accommodating cavity 111. The door assembly 200 is movably provided on the body assembly 100 to open or close the accommodating cavity 111.

[0041] like Figure 1 As shown, in some embodiments, the door assembly 200 includes a first door 210 and a second door 220. The first door 210 is rotatably connected to the cabinet assembly 100 to open or close the freezer liner 130. The second door 220 is rotatably connected to the cabinet assembly 100 to open or close the refrigerator liner 120.

[0042] like Figure 2 As shown, in some embodiments, the cabinet assembly 100 further includes a cabinet body 110, a refrigeration duct 140, and a freezing duct 150. The cabinet body 110 is provided with a receiving chamber 111. The refrigeration duct 140 is disposed within the receiving chamber 111 and communicates with the refrigeration liner 120. The freezing duct 150 is disposed within the receiving chamber 111 and communicates with the freezing liner 130. The freezing duct 150 includes a first connecting wall 151, which is inclined relative to the depth direction of the receiving chamber 111 and is provided with a first air outlet 152 that communicates with the refrigeration duct 150. The refrigeration duct 140 includes a second connecting wall 141, which is inclined relative to the depth direction of the receiving chamber 111 and is provided with a second air outlet 142 that communicates with the refrigeration duct 140. The refrigeration air duct 140 is connected to the freezing air duct 150 , the first connecting wall 151 is in abutment with the second connecting wall 141 , and the freezing air duct 150 and the refrigeration air duct 140 are in communication through the first air port 152 and the second air port 142 .

[0043] In this way, when installing the refrigerator 10, one of the refrigerating air duct 140 and the freezing air duct 150 is first installed in the accommodating cavity 111 of the box body 110, and then the other of the refrigerating air duct 140 and the freezing air duct 150 is installed. The first connecting wall 151 and the second connecting wall 141 are arranged at an angle relative to the depth direction of the accommodating cavity 111. After one air duct is installed in the accommodating cavity 111 of the box body 110, the other air duct can be installed in the accommodating cavity 111 between the boxes by horizontally pushing and placing, so that the first connecting wall 151 and the second connecting wall 141 abut and cooperate, thereby connecting the freezing air duct 150 and the refrigerating air duct 140. This method can connect the freezing air duct 150 and the refrigerating air duct 140 even when the installation space is limited, simplifies the installation process, and improves the installation efficiency of the air ducts. The freezing air duct 150 and the refrigerating air duct 140 are connected through the first air vent 152 and the second air vent 142, and the refrigeration system of the refrigerator 10 can send cold air to the refrigerating liner 120 and the freezing liner 130 through the refrigerating air duct 140 and the freezing air duct 150 respectively to achieve refrigeration.

[0044] In some embodiments, the refrigerator 10 further includes a refrigeration system, which can deliver cold air to the freezing duct 150, and deliver the cold air from the freezing duct 150 to the refrigeration duct 140 through the first air outlet 152 and the second air outlet 142, thereby delivering the cold air to the freezing liner 130 and the refrigeration liner 120, respectively.

[0045] like Figure 3 As shown, in some embodiments, the refrigeration system includes a compressor 11 , a condenser 12 , an evaporator 13 and an expansion valve 14 , and the compressor 11 , the condenser 12 , the evaporator 13 and the expansion valve 14 are disposed in a box assembly 100 .

[0046] Combine Figure 3 As shown, when the refrigerator 10 is in operation, the compressor 11 outputs a high-temperature, high-pressure gaseous refrigerant and delivers it to the condenser 12. The high-temperature, high-pressure gaseous refrigerant is condensed into a medium-temperature, high-pressure refrigerant by the condenser 12. The medium-temperature, high-pressure refrigerant undergoes expansion and throttling by the expansion valve 14, which further reduces its pressure and temperature. The medium-temperature, high-pressure refrigerant then flows out of the expansion valve 14 as a low-temperature, low-pressure liquid refrigerant to the evaporator 13. The low-temperature, low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 13. The cold air generated can enter the refrigerated liner 120 through the freezing air duct 150, thereby lowering the temperature inside the freezing liner 130, making it easier to use the freezing liner 130 to freeze items and achieve refrigeration of the refrigerator 10. In addition, cold air can also enter the refrigeration duct 140 from the freezing duct 150 through the first air outlet 152 and the second air outlet 142, and then be transported to the refrigeration liner 120, thereby lowering the temperature inside the refrigeration liner 120, making it easier to use the refrigeration liner 120 to refrigerate items and achieve cooling of the refrigerator 10.

[0047] like Figure 2 As shown, in some embodiments, the freezer liner 130 is disposed below the refrigerator liner 120 along the height of the refrigerator 10. The refrigerator 10 also includes a first fan (not labeled) disposed in the cabinet assembly 100. The air inlet or outlet of the first fan is connected to the air duct to increase the delivery rate of cold air in the freezing air duct 150 and the refrigeration air duct 140.

[0048] like Figure 2 As shown, the height direction of the refrigerator 10 is the Z-axis direction, and the depth direction of the accommodating cavity 111 is the X-axis direction.

[0049] In some embodiments, the outer side wall of the freezing bin is covered with an insulation layer (not shown). The outer side wall of the freezing bin is covered with an insulation layer (not shown).

[0050] like Figures 4 to 7 As shown, in some embodiments, the first connecting wall 151 is arranged upwardly and obliquely relative to the depth direction of the accommodating chamber 111, and the second connecting wall 141 is arranged upwardly and obliquely relative to the depth direction of the accommodating chamber 111. The first connecting wall 151 includes a first abutting surface 1511 that abuts against the second connecting wall 141, and the second connecting wall 141 includes a second abutting surface 1411 that abuts against the first connecting wall 151. The first abutting surface 1511 faces the freezing liner 130, and the second abutting surface 1411 faces away from the refrigeration liner 120. In this way, when the air duct of the refrigerator 10 is installed, the freezing air duct 150 is first installed in the accommodating chamber 111, and the first abutting surface 1511 of the first connecting wall 151 faces the freezing liner 130, that is, toward the opening of the accommodating chamber 111. At this time, the refrigeration duct 140 is installed into the accommodating cavity 111 through the opening of the accommodating cavity 111, with the first abutting surface 1511 facing the freezing liner 130 and the second abutting surface 1411 facing away from the refrigeration liner 120, so that the refrigeration duct 140 can be horizontally pushed into the accommodating cavity 111 to connect with the freezing duct 150, and the first abutting surface 1511 and the second abutting surface 1411 are in abutment with each other. This simplifies the installation process and improves the assembly efficiency of the refrigerator 10.

[0051] In order to further facilitate the connection between the freezing air duct 150 and the refrigeration air duct 140, as shown in FIG. Figure 7As shown, in some embodiments, the angle formed between the first connecting wall 151 and the depth direction of the accommodating cavity 111 is a, wherein 10°≤a≤30°. The angle formed between the second connecting wall 141 and the depth direction of the accommodating cavity 111 is b, wherein 10°≤b≤30°. And a=b. In the practice of the present disclosure, the researchers found that when the angle formed between the first connecting wall 151 and the depth direction of the accommodating cavity 111 is 10°~30°, and the angle formed between the second connecting wall 141 and the depth direction of the accommodating cavity 111 is 10°~30°, it can facilitate the connection between the freezing air duct 150 and the refrigeration air duct 140. In addition, the angle a formed by the first connecting wall 151 and the depth direction of the accommodating cavity 111 is equal to the angle b formed by the second connecting wall 141 and the depth direction of the accommodating cavity 111, which can further ensure the abutment fit between the first connecting wall 151 and the second connecting wall 141 and avoid the existence of a gap between the first connecting wall 151 and the second connecting wall 141.

[0052] like Figure 7 As shown in the figure, a shown in the figure is the angle formed by the first connecting wall 151 and the depth direction of the accommodating cavity 111, and b shown in the figure is the angle formed by the second connecting wall 141 and the depth direction of the accommodating cavity 111.

[0053] It can be understood that there are many specific implementation methods for the angle a formed by the first connecting wall 151 and the depth direction of the accommodating cavity 111 and the angle b formed by the second connecting wall 141 and the depth direction of the accommodating cavity 111, including 10°, 12°, 15°, 20°, 25°, 27° or 30°, etc.

[0054] In one example, the angle a formed between the first connecting wall 151 and the depth direction of the accommodating cavity 111 and the angle b formed between the second connecting wall 141 and the depth direction of the accommodating cavity 111 are both 15°.

[0055] like Figure 7 As shown, in some embodiments, one of the first connecting wall 151 and the second connecting wall 141 is provided with a stopper 160, and the stopper 160 abuts against the other, so that the first connecting wall 151 and the second connecting wall 141 are relatively fixed via the stopper 160. In this way, when the freezing air duct 150 and the refrigerating air duct 140 are installed in the accommodating cavity 111 of the refrigerator 10, the first connecting wall 151 and the second connecting wall 141 are relatively fixed due to the action of the stopper, thereby further ensuring the connection reliability of the freezing air duct 150 and the refrigerating air duct 140.

[0056] like Figure 7As shown, in one example, the limiting member 160 is disposed around the first air outlet 152 , a portion of the limiting member 160 passes through the second air outlet 142 and abuts against the second connecting wall 141 , and a portion of the limiting member 160 is located in the refrigeration air duct 140 . In this way, when the air duct of the refrigerator 10 is installed, the freezing air duct 150 is first installed into the accommodating cavity 111, and then the refrigerating air duct 140 is installed into the accommodating cavity 111. The limiting member 160 is arranged around the first air outlet 152. When the refrigerating air duct 140 is horizontally pushed into the accommodating cavity 111, the second air outlet 142 of the refrigerating air duct 140 can avoid the limiting member 160, so that part of the limiting member 160 passes through the second air outlet 142, and part of the limiting member 160 is located in the refrigerating air duct 140. The limiting member 160 abuts against the second connecting wall 141 to fix the freezing air duct 150 and the refrigerating air duct 140. The setting of the limiting member 160 will not affect the horizontal pushing of the refrigerating air duct 140 into the accommodating cavity 111. The connection between the freezing air duct 150 and the refrigerating air duct 140 is realized when the installation space is limited, and the installation process is simplified, which can improve the installation efficiency of the air duct. In addition, part of the limiting member 160 passes through the second air port 142 and is located in the refrigeration air duct 140, which can also better transport the cold air in the freezing air duct 150 to the refrigeration liner 120, thereby improving the reliability of cold air transportation.

[0057] It should be noted that there are many specific implementation methods for the limiting member 160 and the freezing air duct 150, including one-piece molding or separate manufacturing and then assembly.

[0058] In one example, the stopper 160 and the freezing air duct 150 are integrally formed, thereby reducing assembly steps and improving assembly efficiency of the refrigerator 10 .

[0059] like Figure 7 As shown, in some embodiments, the cabinet assembly 100 further includes a seal 170, which is sandwiched between the first connecting wall 151 and the second connecting wall 141. Thus, by sandwiching the seal 170 between the first connecting wall 151 and the second connecting wall 141, when cold air is transferred between the freezing air duct 150 and the refrigerating air duct 140, the cold air is prevented from escaping to the outside through the connection between the freezing air duct 150 and the refrigerating air duct 140, thereby reducing the leakage of cold air and saving energy.

[0060] like Figure 7 As shown, in some embodiments, the seal 170 is provided with an avoidance groove 171 to avoid the first air outlet 152 and the second air outlet 142. In this way, the seal 170 is prevented from blocking the first air outlet 152 and the second air outlet 142 during installation, thereby preventing the cold air from being transported between the freezing air duct 150 and the refrigeration air duct 140 from being blocked.

[0061] When installing the air duct of the refrigerator 10, the freezing air duct 150 is first installed in the accommodating cavity 111, and then the sealing member 170 is installed along the limiting member 160. Finally, the refrigerating air duct 140 is installed. The refrigerating air duct 140 is pushed horizontally, and the first connecting wall 151 and the second connecting wall 141 abut against each other to squeeze the sealing member 170, thereby achieving a seal between the freezing air duct 150 and the refrigerating air duct 140. At the same time, the limiting member 160 of the freezing air duct 150 also limits the refrigerating air duct 140, ensuring that the first air outlet 152 and the second air outlet 142 of the freezing air duct 150 and the refrigerating air duct 140 are aligned during the installation process.

[0062] It should be noted that the material of the sealing member 170 can be implemented in a variety of ways, including sponge, rubber, silicone, etc.

[0063] like Figure 7 As shown, in some embodiments, the cabinet assembly 100 further includes a heat insulating layer 180, which is disposed on the inner sidewall of the refrigeration duct 140 and / or the inner sidewall of the freezing duct 150. Thus, by disposing the heat insulating layer 180 on the inner sidewall of the refrigeration duct 140 and / or the inner sidewall of the freezing duct 150, the cold air in the duct can be isolated from the outside world, preventing the outside hot air from causing the temperature of the cold air to rise, thereby improving the cooling efficiency.

[0064] It should be noted that the thermal insulation layer 180 is arranged on the inner wall of the refrigeration duct 140 and / or the inner wall of the freezing duct 150, including the thermal insulation layer 180 being arranged on the inner wall of the refrigeration duct 140, the thermal insulation layer 180 being arranged on the inner side of the freezing duct 150, and the thermal insulation layer 180 being arranged on both the inner wall of the refrigeration duct 140 and the inner wall of the freezing duct 150.

[0065] like Figure 8 As shown, in some embodiments, the freezing duct 150 includes a first cover 153 and a second cover 154, which are connected to form the freezing duct 150, and the refrigerating duct 140 includes a third cover 143 and a fourth cover 144, which are connected to form the refrigerating duct 140. In this way, the freezing duct 150 is formed by assembling and splicing the first cover 153 and the second cover 154, and the refrigerating duct 140 is formed by assembling and splicing the third cover 143 and the fourth cover 144. This method helps to reduce the difficulty of manufacturing the air ducts.

[0066] Of course, in other embodiments, the freezing air duct 150 and the refrigerating air duct 140 may be integrally formed. In this way, the assembly process can be reduced and the assembly efficiency of the refrigerator 10 can be improved.

[0067] See you later Figure 5As shown, in some embodiments, the freezing air duct 150 is provided with a first air supply port 155, and the freezing air duct 150 is connected to the freezing inner container 130 through the first air supply port 155. The refrigerating air duct 140 is provided with a second air supply port 145, and the refrigerating air duct 140 is connected to the refrigerating inner container 120 through the second air supply port 145. In this way, the freezing air duct 150 is connected to the freezing inner container 130 through the first air supply port 155, so that cold air is transported from the freezing air duct 150 to the freezing inner container 130. The refrigerating air duct 140 is connected to the refrigerating inner container 120 through the second air supply port 145, so that cold air is transported from the refrigerating air duct to the refrigerating inner container 120.

[0068] It should be noted that the number of the first air supply ports 155 and the second air supply ports 145 can be set according to actual needs and is not further limited here.

[0069] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this disclosure is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this disclosure shall be included in the scope of protection of this disclosure.
